document.getElementById('waitDia').showModal();

var ticks = 300,
    ticker = setInterval(changeTick,1000);

function changeTick()
{
 document.getElementById('spnTick').innerText = --ticks;
 if (0 === ticks) clearInterval(ticker);
}

#waitDia
{
 position:absolute;
 left:0 !important;
 top:0 !important;
 width:100vw !important;
 height:100vh !important; 
 padding:0; 
 min-width:100vw;
 min-height:100vh; 
 background-color:transparent !important;
}

#waitDia::backdrop{background-color:rgba(127,127,127,0.2);}
